GASOLINE TORCH.

Application filed June 4, 1926.

This invention relates to a gasoline torch and it consists in the novel features hereinafter described and claimed.

An object of the invention. is to provide a combination melting pot and babbitt ladle and gasoline vapor torch with which the babbitt can be melted and poured while the flame is under the bowl of the ladle and while the metal is being poured. If desired the ladle may be removed from the torch.

With these and other objects in view the torch comprises a body having a head portion and a shank portion and with a handle grip attached to the shank portion The head of the body is divided by fi llOlTlZOIllZZll partition wall into upper and lower chambers and the shank and handle grip are provided with a passageway there being a valve provided upon the shank for controlling or regulating the movement of gasoline vapor through the passageway. The sald passageway communicates at its inner end w1th the uppermost chamber in the head. A by-pass passageway connects at one end with the first mentioned passageway and with the lower chamber in the head. Burner nozzles are screw threaded in the partition wall of the head and their upper end portions passed through openings provided in the top of the head. The burner nozzles are provided with ducts which communicate at their lower ends with the interior of the lower compartment in the head and wicks are embedded in the upper side of the head and surround the burner nozzles. Means are provided for leading vaporized or carbureted air into the first mentioned passageways through the handle grip.

In the accompanying drawing:

Figure 1 is a top plan view showing a ladle mounted upon the gasoline torch;

Figure 2 is a longitudinal vertical sectional View of the torch:

Figure 3 is a transverse sectional view thereof cut on the line 3-3 of Figure 2;

Figure 4 is a fragmentary side elevational View with parts in section of the means for conducting the vapor and carbureted air to the torch.

As illustrated in the accompanying drawing, the ladle includes a bowl 1 having a handle 2 attached thereto. The body of the torch includes a head 3, a shank portion 4 having a handle, grip 5 attached thereto. The head 3 is hollow and is provided in its Serial No. 113,715.

interior 1 with a horizontal partition wall which divides the interior-of the head into chambers 7 and 8. A passageway 9 leads through the shank 4 and handle grip 5 and communicates at its inner end with the chamber 7. A valve 10 is turnably mounted in the shank 4 and is arranged to control the flow of vapor through the passageway 9. A by-pass passageway 11 connects at one end with the passageway 9 and at its other end communicates with the interior of the chamber 8.

Burner nozzles 12 pass through the upper and lower sides ofthe head 3 and are provided at points between their ends with screw threads 13 which are screwed into the partition wall 6. The upper end portions of the nozzles 12 are reduced in diameter and passvthrough relatively large openings 14 in the top wall of the head 3. W icks 15, preferably of wire netting, areembedded in the upper portion of the top wall of the head 3 and surround the upper ends of the nozzles 12 and substantially fill the upper ends of the openings 14. The nozzles 12 are provided with ducts 16 which open at the upper ends of the said nozzle and the lower ends of the ducts l6 communicate with the interior of the chamber 8 in the head 3.

A nipple 17 is connected with the end of the handle grip 5 and connnunicates with the passageway 9. The means for supplylng vaporized air to the torch consists of a compressed air tank'18 having a pressure gauge 19 mounted thereon and a pipe 20 connected with the top side thereof. The pipe 20 is provided with valves 21 and 22. One end of the pipe 20 enters a. gasoline tank 28. A pipe 24 also communicates with the gasoline tank 23 and may be connected with the nipple 17. A by-pass pipe 25 connects the pipe 20 with the pipe 24 and is provided witha valve 26. Stand members 27 are connected with the intermediate portion of the shank 4 and are provided at their upper ends with shelf portions 28 in which the handle 2 of the ladle fits. Pins 29 may be provided for fixing the handle 2 of the ladle to the shelf portion 28 as best shown in Figures 2 and 3 of the drawing.

In use the parts are assembled as shown in Figure 2 of the drawing and the metal to be melted is placed in the bowl 1 of the ladle. When the valves 21 and 22 are open the airpasses from the tank 18 through the pipe 20 into the tank 23. The said air is carbureted in the tank 23:and.the'carbureted air passes through'the pipe 24e and nipples 17 into the passageway 9 of the handle and shank of the torch. When the valve 10 is at an open position as shown in Figure 2 with relation to the passageway 9, the vapor or carbureted air passes from the passageway 9 into the compartment'Tand from the passageway 9 through the passageway 11 into the compartment 8 of the head of the torch. The vapor'w-hich enters the compartment/7 passes up through the openings {14 and through the wicks 15 andis ignited under the howl 1 of the ladle Atthe same-time the'vapor and carbureted air, which is admitted into the chamber '8 passesintothe ducts 16 of the nozzle "12, thence up through the said ducts to thepoint of ignition immediately below 'thebowl 1 of the ladle. hen the valve 10 is open theloowl ofthe ladle is subjected to a veryhot-fiame. \Vhen the valve 10 is closed, the-fuel is cut'oii'from the upper chamber of the header the torch and the flame is supplied by fuel which passesthrough'the'ducts 16 only and consequently the fiamebelow thebowlof the ladle is 'not so hot.

hen it is desired to pourthe metal which has been melted in the'bowl 1 ofthe ladle, the handle grip ois grasped whilethe-handle ofthe ladle isretainedinthe shelf portions 28 of the stand 27 At the same time, the flame may be permitted to burnunder the bowl of the ladle. Th-Listheladle and the'torch may he turned and the metal-may be poured and in view of the fact that the flame remains in close proximity'to' the bowl of the. ladlel the metal will not have a chance to cool off during such time asi-tiis being poured from the bowlof the ladle.

From the foregoing description, taken m conjunction with the accompanying drawing 'it will be seen that the-combination melting pot andgasolinevapor burneror torch of simple andldurable structure is provided andthatthe same may be-conveniently and economically used for melting and pouring metals.

Having described the invention What is claimed is 1. A gasoline vapor burner'comprisin'ga body having a head portion-and a shank passageways which communicate one with the other and which communicate at their inner ends with the chambers respectively,

a valve for controlling the passage of vapor through one ofthe, passageways, and burner nozzles passing through the upper and lowerwalls of'the head and engaging in the partitionwvall of thehead the lower ends of the nozzles being closed, the upper ends of the burner-nozzles being spaced from the surfaces ofthe walls ofthe upper side of the head, wicks surrounding the discharge ends of the'burnernozzles, said nozzles hav ing ducts whichconnnunicate at their lower end with the lower -coinpartment of the head.

'2. A a gasoline torch comprising a head having a shank provided with a valve controlled passageway, the head being hollow and having an interiorly located horizontally disposed partition wall dividing the sameintoupper and lower compartments, burner nozzles passing through the upper and. lower walls of I the head and having screw thread engagement in the partition wall'the lower endso'f said nozzles being closed, said burner nozzles having ducts which communicatewvith the lower compartment of the head 'and means'for admitting vapor into the lower compartment of the head.

3 A gasoline torch comprising a head having a 'shankjprovided with passageways oneoi": which is controlled by a valve, the headibeing hollow and having an interiorly located horizontally disposed partition wall dividing the same into upper and lower compartments, said partition wall-being located between said passageways, burner nozzlesjpassing-through the upper and low er walls "of the head and having screw thread engagement in the "partition wall, the lower ends of said nozzles being closed. said burner nozzles having ducts which communicate with the lower, compartment of the head.

In testimony whereof I afiix my signature.
